Description
Technical field
The utility model relates to technical field of bridge engineering, particularly relates to a kind of assembling hollow slab beam bridge construction.
Background technology
Assembling hollow slab beam structure has that highly low, transporting and hoisting is convenient, speed of application is fast and the advantage such as construction costs is low, in bridge engineering, is especially widely used in small bridge engineering.
But, assembling hollow slab beam of the prior art is generally connected by the articulated structure being arranged at hollow slab beam sidepiece, and the lateral connection poor-performing between hollow slab beam, under Heavy Traffic repeated action, hinge seam place is easily destroyed and lost efficacy, and then causes beam body to be destroyed.
In order to solve above-mentioned technical problem, those skilled in the art are reinforced assembling hollow slab beam by diverse ways, and method conventional at present has:
1) bridge floor strengthening course reinforcing method.This reinforcement means is easy to maintenance, but engineering quantity is large, cost is high.Meanwhile, cutting and again laying of concrete pavement all needs long-time close traffic, often cannot implement because traffic organization difficulty is large in high-traffic area.
2) external prestressing method.Generally at the bottom of beam, arrange transverse prestress, maintenance effect is better.But sensorial effects is not good, easily affect public psychology, be unfavorable for extensive use in Urban Bridge.
3) beam bottom pouring mortar reinforcing method.Adopt after reinforcing in this way, the effect of the aspects such as the long-term adhesion energy of the performance of the structure glue of solidifying under Vibration Condition, structure glue and beam slab side is not also confirmed, and cost is high, cannot on a large scale in promote the use of.
In view of the defect of above-mentioned various conventional reinforcement means, need higher, the concrete pavement of a kind of bearing capacity of research badly and abolish the assembling hollow slab beam bridge construction that area is less, effectively can intercept hinge seam cracking.
Utility model content
Because the above-mentioned defect of prior art, the utility model proposes that a kind of bearing capacity is higher, concrete pavement abolishes the assembling hollow slab beam bridge construction that area is less, effectively can intercept hinge seam cracking.
For achieving the above object, the utility model provides a kind of assembling hollow slab beam bridge construction of transversely strengthening, at least comprises multiple assembling hollow slab beam, is connected as one between multiple described assembling hollow slab beam by the articulated structure being arranged at its sidepiece; The top of described assembling hollow slab beam is provided with layer of concrete, and described layer of concrete is mated formation and is also provided with the transversely strengthening structure of multiple high strength in scope, multiple described transversely strengthening structures being horizontally arranged at interval along bridge construction; Described transversely strengthening structure is the high performance concrete including high-performance fiber, is provided with tendon in described high performance concrete.
In some preferred embodiments, the transversely strengthening band of described transversely strengthening structure to be width be 300-1000mm.
In some preferred embodiments, the width of described transversely strengthening band is 500mm.
In some preferred embodiments, the described transversely strengthening band on assembling hollow slab beam described in each is five.
The beneficial effects of the utility model:
Said structure design of the present utility model, multiple ruggedized construction is arranged at intervals with in layer of concrete mats formation scope, effective obstruct has been carried out in the cracking of the hinge seam between the arranging assembling hollow slab beam of ruggedized construction, expansion and extension, enhances the bearing capacity of bridge construction.
Said structure design of the present utility model, carry out concentrating reinforcing to bridge construction owing to adopting transversely strengthening band, drastically reduce the area and abolish area to layer of concrete when transversely strengthening band is mated formation, reduce the difficulty of traffic organization during construction, improve the exploitativeness of construction.
Be described further below with reference to the technique effect of accompanying drawing to design of the present utility model, concrete structure and generation, to understand the purpose of this utility model, characteristic sum effect fully.
Accompanying drawing explanation
Fig. 1 is the plane structure schematic diagram of the utility model one embodiment.
Fig. 2 is that the master of Fig. 1 cuts open structural representation.
Detailed description of the invention
As depicted in figs. 1 and 2, present embodiments provide a kind of assembling hollow slab beam bridge construction of transversely strengthening, as shown in Figure 1, the assembling hollow slab beam bridge construction of transversely strengthening comprises multiple assembling hollow slab beam 1, articulated structure (not shown) by being arranged at its sidepiece between multiple assembling hollow slab beam 1 connects as one, and forms hinged seam 2 between assembling hollow slab beam 1.
As shown in Figure 2, the top of assembling hollow slab beam 1 is provided with layer of concrete 4, each assembling hollow slab beam 1 that layer of concrete 4 is mated formation in scope is also provided with transversely strengthening band 3, five transversely strengthening bands 3 being horizontally arranged at interval along bridge construction being used as transversely strengthening structure of five high strength.Above-mentioned transverse direction is the width of bridge construction.
Said structure designs, multiple ruggedized construction is arranged at intervals with in layer of concrete mats formation scope, the expansion of the hinge seam cracking between the arranging the articulated structure of assembling hollow slab beam of ruggedized construction, extend and carried out effective obstruct, enhance the bearing capacity of bridge construction.Test shows, due to the setting of ruggedized construction, when the hinge seam place between the articulated structure of assembling hollow slab beam is all damaged, bridge construction is still in a safe condition, thus improves the bearing capacity of bridge construction, improves the safety factor of bridge construction.
Transversely strengthening band 3, for including the high performance concrete of high-performance fiber, is provided with tendon in high performance concrete.The above-mentioned material of transversely strengthening band 3 is arranged, and substantially increases the stress-bearing capability of transversely strengthening band 3.In addition, carry out concentrating to bridge construction owing to adopting transversely strengthening band and reinforce, drastically reduce the area and abolish area to layer of concrete when transversely strengthening band is mated formation, reduce the difficulty of traffic organization during construction, improve the exploitativeness of construction.
A large amount of experimental verifications shows, when the width of transversely strengthening band is 300-1000mm, namely can meet the requirement to bridge strengthening, also constructability, saves material, and the width preferably adopting transversely strengthening band is 500mm.
Embody rule situation of the present utility model is as follows:
First, determine layer of concrete 4 mat formation in scope needed for the position of transversely strengthening band 3 of mating formation; Then, abolish the required layer of concrete laying transversely strengthening band 3 one by one, and transversely strengthening band is arranged in this place.Adopting uses the same method lays remaining transversely strengthening band.When adopting above-mentioned laying method, can lay at night, thus decrease the obstruct to the traffic of laying section, greatly reduce the difficulty of traffic organization, improve the convenience of construction.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without the need to creative work.Therefore, all technician in the art according to design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should by the determined protection domain of claims.
